2. Process description of a coalfired power plant. A coalfired power plant burns coal to produce electricity. In a typical coalfired plant, there are pulverisers to mill the coal to a fine powder for burning in a combustion chamber of the boiler. The heat produced from the burning of the coal generates steam at high temperature and pressure.

WhatsApp: +86 18203695377A thermal power plant is a large facility that converts heat energy into electric power. The heat energy is typically generated by burning fossil fuels, such as coal, oil, or natural gas. The hot combustion gases are used to heat water in a Steam boiler, which produces steam.

Worldwide there are over 2,400 coalfired power stations, totaling over 2,000 gigawatts capacity. [1]
WhatsApp: +86 18203695377Biomass power plants are very similar in operation to coalfired power plants, as illustrated in Figure 1. The biomass is delivered to the plant where storage piles or silos accommodate extra biomass that is not immediately fed to the plant.

WhatsApp: +86 18203695377Natural gas power plants are cheap and quick to build. They also have very high thermodynamic efficiencies compared to other power plants. Burning of natural gas produces fewer pollutants like NOx, SOx and particulate matter than coal and oil. [2] On the other hand, natural gas plants have significantly higher emissions than a nuclear power plant.
WhatsApp: +86 18203695377Why a combined cycle power plant? The simple reason efficiency. When compared to a traditional coal or gas fired plant (boiler or simple cycle combustion turbine), a combined cycle plant's overall efficiency can be 20 30% greater. This means that fuel use is 20 30% less and the fuel cost per megawatthour is 20 30% lower.

WhatsApp: +86 18203695377How a Coal Plant Works. Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over. Here's a real ...
